Implement connectivity heatmap

[EPajares]

Goal of this issue

We can create the isochrone area size needed for the connectivity heatmap from the traveltime matrices. I wonder where we save it, though. I believe the best would be to save it in the grid_calculation table, as we cannot create the isochrone shapes from the matrices each time on the fly.

The steps to get to the areas.

[EPajares]

One thing. We might need the shapes again to intersect with the AOIs. While this will be a separate function, we could reuse the isochrone shapes. For the AOI we need one every minute isochrone so if it is 20 minutes we have 20 isochrones.

We can compute the isochrone like this and then for the connectivity heatmap, we only use the 5, 10 and 15 minute isochrone.

The files are ready now. I'm going to config the heatmap endpoint for it.

[metemaddar]

I think we can remove the max_traveltime from heatmap_config as we have max_traveltime in main heatmap_settings.

[EPajares]

I think we should keep it in heatmap_config. As I think we should remove it from the heatmap_settings instead. As for the other heatmaps we also have it inside the heatmap_config
